I took the placement test. I can stay 3 months without a visa. I can apply for a visa once I'm there to stay longer. I got the 2-page visa PDF file... looks painless enough to fill out.
I have two choices of housing: through the Goethe Institute, or with Calliste (her post). But that's up to her roommates wanting me there or not. The advantage of being there is that there's DSL, so I could work on LJ easily. The net access through the Goethe Institute would be pay-by-minute in some lab, it seems.
Evan did the Goethe Institute and highly recommends it, so that gives yet more impetus to go.
This would rock. Note to self: get moving on this. I'm going to call the Goethe Institute tomorrow and ask them a few questions.
